188 # Assemble a .s file
, then run some utility
on it and check the output.
190 # There should be an assembly language file named FILE.s in the test
191 # suite directory
, and a pattern file called FILE.d. `run_dump_test
'
192 # will assemble FILE.s, run some tool like `objdump', `objcopy
', or
193 # `nm' on the .o file to produce textual output
, and
then analyze that
194 # with regexps. The FILE.d file specifies what
program to run
, and
195 # what to expect in its output.
197 # The FILE.d file begins with zero or more option lines
, which specify
198 # flags to pass to the assembler
, the
program to run to dump the
199 # assembler
's output, and the options it wants. The option lines have
204 # OPTION is the name of some option, like "name" or "objdump", and
205 # VALUE is OPTION's value. The valid options are described below.
206 # Whitespace is ignored everywhere
, except within VALUE. The option
207 # list ends with the first line that doesn
't match the above syntax
208 # (hmm, not great for error detection).
210 # The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of
211 # two
-element lists. The first element of each is an option
name, and
212 # the second additional arguments to be added
on to the end of the
213 # option list as given in FILE.d.
(If omitted
, no additional options
216 # The interesting options are
:
219 # The
name of this test
, passed to DejaGNU
's `pass' and `fail
'
220 # commands. If omitted, this defaults to FILE, the root of the
221 # .s and .d files' names.
224 # When assembling FILE.s
, pass FLAGS to the assembler.
227 # The
name of the
program to run to analyze the .o file produced
228 # by the assembler. This can be omitted
; run_dump_test will guess
229 # which
program to run by seeing which of the flags options below
235 # Use the specified
program to analyze the .o file
, and pass it
236 # FLAGS
, in addition to the .o file
name. Note that they are run
237 # with LC_ALL
=C in the environment to give consistent sorting
241 # Assemble the file SOURCE.s.
If omitted
, this defaults to FILE.s.
242 # This is useful
if several .d files want to share a .s file.
245 # An error with message matching REGEX must be emitted
for the test
246 # to pass. The PROG
, objdump
, nm and objcopy options have no
247 # meaning and need not supplied
if this is present.
249 # Each option may occur at most once.
251 # After the option lines come regexp lines. `run_dump_test
' calls
252 # `regexp_diff' to compare the output of the dumping tool against the
253 # regexps in FILE.d. `regexp_diff
' is defined later in this file; see
